Hello. I have a method to print the current view of a table, but is it
somehow possible to print the whole table and not only a cut-out of it?
Here is my code to print the current cut-out of the table I see on the
screen:
print.addSelectionListener(new SelectionAdapter(){
public void widgetSelected(SelectionEvent e){
Point tableSize = table.getSize();
final Image tableImage =
new Image(Display.getCurrent(), 750, tableSize.y);
GC tableGC = new GC(table);
tableGC.copyArea(tableImage, 0, 0);
Shell shell = new Shell();
PrintDialog dialog = new PrintDialog(shell);
PrinterData data = dialog.open();
Printer printer = new Printer(data);
ImageData tableImageData = tableImage.getImageData();
tableImageData.transparentPixel = -1;
int scaleFactor = 5;
Rectangle trim = printer.computeTrim(-500, -500, 0, 0);
if (printer.startJob("DeployHistory-Print")) {
GC gc = new GC(printer);
if (printer.startPage()) {
gc.drawImage(
tableImage,
0,
0,
tableImageData.width,
tableImageData.height,
-trim.x,
-trim.y,
scaleFactor * tableImageData.width,
scaleFactor * tableImageData.height);
printer.endPage();
}
printer.endJob();
}
printer.dispose();
tableGC.dispose();
}
});

Hey,
I would otherwise be happy to post the code, but
I have a rather large printing infrastructure that this code
works off of, and it's not something where I can just post
the contents of a method.
Regarding your question though, there are two solutions:
1) Pre-calculate the max column width (using text extents)
for each row of a page. Then make column 2 (for instance)
start at the same location for each row where the "x" of
column 2 is greater than the max width of column 1.
2) Instead of drawing row 1, then row 2, then row 3, reverse your
loop, and draw by columns. that way you don't have to
pre-calculate
the max width of every column...you draw column 1 first keeping
the maximum width of all column 1 for a given page as you draw
each cell. Then when you get to column 2, you know the the
max "x", so just continue your look, setting your column 2
starting
"x" to be greater than that max value.
I actually chose number 2 in my implementation.
Hope that helps.

Hi,
sorry for the late answer. You could try KPrint
see http://www.kupzog.de/fkmk_uk/Programming/Downloads/downloads .html
This is a SWT formatted printing utility that also supports printing SWT
tables (and KTables).
Regards,
